  • Update Regarding the DRINC Portal

To be included on the California Registration Listing (posted online), it is required that you provide specific information in electronic format for posting by the SWRCB. This information to be posted by the SWRCB consists of:

Note: If the Product Data Sheet for a device is still current, there is no need to upload a new one.

SWRCB Posting of Performance Data Sheet / Product Worksheet

  1. The Performance Data Sheet that has been reviewed by the Certification organization for this model.
  2. If the Performance Data Sheet is embedded in the Product Manual, we require a 'stand-alone' version of the Performance Data sheet which would typically be one to three pages in length. We will NOT post the entire Product Manual.
  3. Here is list of the information that must be provided

    • The name, address, and telephone number of a contact person for the manufacturer. This is meant to be contact information for the consumer.
    • The name and model number of the water treatment device, and any other product identification, used by the manufacturer to describe the water treatment device or treatment component.
    • Each specific contaminant claimed to be removed or reduced by the device.
    • A summary of the results, and information for the consumer on retesting of the device for contaminant reduction that is required by the certification organization to maintain the device certification listing.
    • The service flow rate in gallons per minute or gallons per day or the production rate in gallons per day.
    • The rated service life of the water treatment device, if applicable.
    • The general use conditions and needs of the device, including, but not limited to, its maximum turbidity and the bacteriological quality of source water. Disclaimers on source water limitations, other disclaimers on specific contaminants such as Arsenic as appropriate.
    • The model or part number of components that must be periodically or routinely replaced to maintain the effectiveness of the device.
    • The maximum and minimum operating temperature of the device in degrees Fahrenheit and degrees Centigrade.
    • The maximum and minimum operating pressure of the device in pounds per square inch and kilograms per square centimeter.
    • A reference to the device's owners' manual for general operation and maintenance requirements and the manufacturer's warranty. May also include a link to the manual, if posted online.
Note: In addition to these requirements, SWRCB staff will review these documents to ensure that they are free from excessively small font sizes and that important use conditions are clearly stated. We expect that the Certification organization will ensure that the Performance Data Sheets and other product literature are appropriately sized for consumer use as part of their Certification process. As additional information, please note that Federal Guidelines stipulate that consumer product literature be not less than 1/16th of an inch in height.

Information on Upcoming Product Labeling Requirements

Effective July 1, 2015 California law pertaining to water treatment devices includes two new requirements for product labeling and packaging. Additional information on these requirements is below:

  • Exterior Packaging Requirement Section (HSC Section 116835 (b)) - After July 1, 2015, the exterior packaging of a water treatment device for which a health or safety claim is made, and that is offered for sale in a retail establishment in California, shall clearly identify the contaminant or contaminants that the device has been certified pursuant to subdivision (a) to remove or reduce. If a device has been certified to remove or reduce more than five contaminants, at least five contaminants shall be listed on the exterior packaging followed by a statement directing consumers to visit the manufacturer’s Internet Web site to obtain information regarding additional contaminants that the device is certified to remove or reduce. Regarding this requirement, please note that this list of contaminants should be of a placement and font size/color such that it is legible to the consumer (i.e. font should not be excessively small).
  • Requirement for Decal (Label) Affixed to Device (HSC Section 116835 (c)) - After July 1, 2015, the manufacturer of a water treatment device for which it makes a health or safety claim shall include with each water treatment device offered for sale in California a decal that may be affixed to the device by the consumer that states, at a minimum, the following:
  • “Please refer to the owner’s manual for proper maintenance and operation. If this device is not maintained and operated as specified in the owner’s manual, there is a risk of exposure to contaminants. For more information, visit the manufacturer’s Internet Web site at Manufacturer’s Internet Web Site or the [State of California Device Registration Program website]”

    Please note the following additional clarification regarding this requirement:

  1. A permanent label in lieu of the decal is acceptable. The label may be placed onto the product by the manufacturer or included so that it may be placed by the consumer. The label must be of a placement and font size/color such that it is legible to the consumer.
  2. Include information within the owner's manual alerting the consumer to the need for proper maintenance and operation. The addition of this language to the product manual may be made during the next product recertification cycle. Manufacturers may choose the exact wording for this notice. The language should include the following verbiage or equivalent from the statute: "If this device is not maintained and operated as specified in the owner's manual, there is a risk of exposure to contaminants"..
  3. For some products with very little surface area, the manufacturer may be concerned that the decal will be too small to be legible. In that case, the manufacturer may choose an alternative means of meeting the intent of this requirement. Options may include a hang tag, including the statement on the cartridge, or allowing the customer to affix the label to the wall, refrigerator or other surface that the consumer may select
  4. The label / decal must include the basic language specified in the statute but refer to the website of the State Water Resources Control Board as follows:

Please refer to the owner’s manual for proper maintenance and operation. If this device is not maintained and operated as specified in the owner’s manual, there is a risk of exposure to contaminants. For more information, visit the manufacturer’s Internet Web site at Manufacturer’s Internet Web Site or the California State Water Resources Control Board’s Internet Web site at www.waterboards.ca.gov.”
